Weather: Āwhitu Peninsula road collapses in landslide caused by Cyclone Gabrielle

A road has collapsed on Auckland's Āwhitu Peninsula after a massive landslide caused by Cyclone Gabrielle.

The collapse happened on Lighthouse Rd, caused by relentless heavy rain that's lashed the North Island in recent days.

Images supplied to Newshub show the extent of the slip on the peninsula, which was also hit hard by severe weather in Auckland just weeks ago. 

The Āwhitu Peninsula is the same area where a bach collapsed after heavy rain on February 1, injuring three people.

Earlier on Tuesday, Prime Minister Chris Hipkins said at a news conference the latest weather emergency had displaced many families while many more were without power, adding the cyclone had caused extensive damage.

The Government has declared a national state of emergency in the wake of the cyclone.

"It will take us a wee while to get a handle on exactly what's happened," Hipkins told reporters.

"I want to acknowledge those families that are functioning without power and, in some cases, without communications.

"We'll be working as quickly as we can with the relevant agencies to make sure we're getting the power back on to make sure we're restoring communications as quickly as we possibly can."
